Life and works 
The Sams brothers opened a specialised macrobiotic foodshop, Ceres Grain, the following year. To spread the word about Ceres and SEED, Greg published three editions of a specialised magazine called 'Harmony'. During the 1970s, Greg, his brother Craig and their father Ken edited and published a magazine called 'Seed, the Journal of Organic Living' over a seven-year period.
In 1982, Greg left Whole Earth Foods with his brother who went on to become chairperson of the Soil Association, and develop Green & Blacks organic chocolate with his partner. Greg went on to invent the first veggie burger, which he christened VegeBurger, which became a worldwide success.
In 1990, Greg opened in London Strange Attractions, the only shop in the world dedicated to the chaos theory. He became famous for his fractal art, his designs adorning postcards, t-shirts and textiles all over the world.
An enthusiast of the counterculture movement, such as the non-violent direct action street reclaiming events in the UK and elsewhere such as Reclaim the Streets, Greg Sams began writing books that were promoted at these events, as well as during various trance music, psytrance and acid techno raves and free parties around the UK. Uncommon Sense - the State is Out of Date was published in 1998 to great acclaim, showing the importance of chaos theory in the way we live - and should live - our lives. In 2006 he completed a new book, Sun of gOd - Discover the Self-Organizing Consciousness That Underlies Everything.
Greg has been a regular on the world music festival scene ever since he provided the macrobiotic catering at the first Glastonbury Festival in 1970. A regular of events such as Pendragon at the now defunct Tyssen Street Theatre Factory, he still travels to worldwide music festivals, solar eclipses, and festivals such as The Glade. He was interviewed on the Liquid Crystal Vision film which has been viewed at many festivals worldwide.
